Sounds and Vocal Behavior

Vocalizations

Undescribed, and largely silent. Probably produces hisses and various grunting calls, as described for Turkey Vulture (Cathartes aura) (Kirk and Mossman 1998).

Nonvocal Sounds

None reported. Perhaps similar to Turkey Vulture (Cathartes aura), nestlings of which stomp the feet if disturbed, which may produce a loud sound if the nest chamber is resonant (Kirk and Mossman 1998). Nestlings of Turkey Vulture also may produce a flapping sound with the wings when disturbed, as part of a bluff attack (Kirk and Mossman 1998).
